Abstract

L'invention concerne un logement d'appui-tête destiné à être utilisé dans un dossier (1) d'un siège de véhicule. Le logement d'appui-tête présente au moins un tube récepteur (4) pouvant être inséré dans le dossier (1), avec une cavité de tube interne (4a) pour recevoir une tige d'appui-tête (3) réglable en hauteur, et une partie de fixation (7) avec une ouverture de réception (8) ouverte vers le haut, pour recevoir une extrémité inférieure (9) de la tige d'appui-tête (3). La tige d'appui-tête (3), lorsque son extrémité (9) de tige d'appui-tête est reçue dans la partie de fixation (7), est logée de manière imperdable dans le tube récepteur (4). Conformément à l'invention, la partie de fixation (7) est fixée à l'extrémité inférieure du tube récepteur (4), et entre le tube récepteur (4) et la partie de fixation (7) est réalisée une liaison libérable (6) de préférence un moyen arrachable. La liaison libérable est libérée de préférence lors de l'insertion de l'extrémité (9) de la tige d'appui-tête dans la partie de fixation (7), par sollicitation en traction, notamment par déchirure. L'opération d'insertion s'effectue avantageusement en créant un assemblage par friction et/ou par complémentarité de forme entre l'extrémité (9) de la tige d'appui-tête et la partie de fixation (7).
